This room is constructed with tumbling gears housed in the walls and pressure plates across the floor near the middle of the room. When triggered the room lurches suddenly on its side, rotating 90 degrees. Those in the room are hurled toward the double line of spears on the west wall. On the following round the smiths charge across the room (falling on pulley-suspended cables) and smash into anyone pinned by the spears (a DC 15 Reflex save avoids the hammer wielding statues). The chamber rights itself automatically one minute later, resetting the trap.
